This should not come as too much surprise to anyone who's been following my posts for the last few days, but my next book chapter will be a little bit different. jamesblandecon.github.io/StructuralBa... #EconSky

Harold Zurcher's policy function for replacing bus engines. Estimated in Stan. Shaded regions show 95% Bayesian credible regions. Dashed curve is the logit fit through the data. Estimated with fixed discount factor of 0.9 More to come. Watch this space! #EconSky #Structural #DynamicProgramming

Got my hands on some old data! I feel like this is a rite of passage for structural econometricians that I haven't yet had a crack at. Going to have a go at getting this to work in Stan

A new chapter is available in my free online book! #EconSky jamesblandecon.github.io/StructuralBa...

Hello #EconSky, and in particular experimental economists. Do you have a paper where you estimate preferences and then use these estimates on the right-hand-side of a regression (or logit, tobit, etc)? I'm looking for a good example dataset for a chapter idea I have for my book.

@profanity.accountant, what's my score?

I tried something that didn't work too well, so I wrote a paper about it. a thread ... github.com/JamesBlandEc... #EconSky

Does anyone want a survivorship bias shortbread

Bring it! The draft is coming together!

I found out that something doesn't work very well. In the interest of not burying it so that someone else goes down this rabbit hole again, maybe I will try to write a paper.

New version of a working paper: "Meta-study in the shadow of the future: the effect of continuation probability on strategies" papers.ssrn.com/sol3/papers.... I have re-done the analysis with an expanded list of strategies #EconSky

Celebrating a very positive R&R today 😀😀 #EconSky

I am obsolete. A thread. #ChatGPT #EconSky I might be late to the game with this, but here we go. Today I asked ChatGPT to write some code for me. This is something I've been avoiding for a while. I *like* coding. The act of it brings me joy, but I was curious ... github.com/JamesBlandEc...

Weird question: For strategy frequency estimation (SFEM), does anyone have a fast way to code up how many times a participant has followed a strategy? This is really easy for (say) memory-1 strategies, but for strategies with more than 2 states I can't see the matrix wrt doing it fast #EconSky

New version of my working paper: "Meta-study in the shadow of the future: the effect of continuation probability on strategies" papers.ssrn.com/sol3/papers.... I have added another experiment to the meta analysis, bringing it to a total of eleven experiments.

Getting ready to present my work at Purdue Also looking forward to catching up with a whole lot of friends and colleagues from my PhD program! link to paper here: papers.ssrn.com/sol3/papers....

Getting ready to teach my course. This time at The University of Pittsburgh 😀 #EconSky

New working paper: "Rank-dependent utility preferences need not be convex preferences" papers.ssrn.com/sol3/papers.... Really a note, it's 3 pages #EconSky ...

The middle child (10) is not only able to detect the panchetta in the shopping bags before they're brought in (this deducing that carbonara is in his future), but can also recognize when I've accidentally ordered 50% more panchetta than I usually do.

When I, the econometrician, need to have beliefs over people's prior beliefs, it leads to variable names like this. #EconSky

Econ PhD students doing experiments: are you doing something interesting with your econometrics? I will read your paper and give you comments! Structural and/or Bayesian not necessary #EconSky

I had a great time presenting material from my book in the Workshops for Ukraine series today (sites.google.com/view/dariia-...). Thanks @dariia.bsky.social for organizing such an amazing series.

My book is now available as a PDF here: papers.ssrn.com/sol3/papers.... It will still always be available in HTML (here: jamesblandecon.github.io/StructuralBa...), and HTML will be my preferred version (the tables look better).

Getting ready for my Workshop for Ukraine. Coming up in a bit under two hours!

An amazing paper, and related to some work I am doing on optimal experiment design. Well worth a read! #EconSky

Thanks to the @ecscienceassoc.bsky.social team for an amazing N American meeting. I am glad that there is room for me in this space!

Another new blog post! This time, I resurrect some data collected with my kids during COVID and give it the structural Bayes treatment #EconSky #RStats #Stan jamesblandecon.github.io/posts/2025-0...

Working on another blog post. It's another angle accuracy model, but this time with Nerf darts and data I collected with the kids during COVID lockdown. #RStats #EconSky

A new blog post! NFL field goal attempts: Geometry and Stan This is an extension of some work I did a few years ago. Now I am using newer data and a richer statistical model. #RStats jamesblandecon.github.io/posts/2025-0...

In some non-econ news, I saw The Darkness in Detroit last night. Much fun was had!

On October 16th I will be presenting material from my book in the Workshops for Ukraine online workshop series. Details here 👇👇 sites.google.com/view/dariia-... #EconSky #RStats #TeachBE

#EconSky hive mind, and experimental and behavioral peeps in particular: I've been working on a couple of chapters for my book, and am really enjoying writing them at the moment. If there's something you'd like to see in it, I'm open to suggestions! jamesblandecon.github.io/StructuralBa...

an amazing resource for everyone in behavioral/experimental econ and beyond

Looks AMAZING James! Wow what a resource! @jamesbland.bsky.social
